Explosive horsepower developed from the most cutting edge technology bring the 450 SEF-R into life. Torque your way through the rev range with instant power on demand and plenty in reserve. Horsepower combined with the latest French ergonomics, technology and Brembo stopping power make the 450 SEF-R a machine not to be reckoned with.
100% new for 2015 the 450 uses the proven formulas from the brand’s low cubic capacity models. The chassis, while specific for housing the large motor, maintains the ergonomics of the 300 and 250 SEF. The frame is a development of the highly-reputed semi-perimeter Sherco frame in chromium molybdenum steel made of mechanically welded parts. An option selected by Sherco to offer a maneuverability/stability compromise perfectly suited to the highly diverse conditions that may be encountered in the enduro.
Sherco remains loyal to the equipment manufacturers with the best reputations: WP for suspensions, Brembo for brakes, and Trail Tech for the computer (with maintenance indicator). The next generation motor is more compact and higher-performance. The timing uses cascading pinion gears and chains. The selector drum is made of aluminum and the valves are steel for greater longevity and extreme enduro use.
Power is provided by the Synerject system, developed specifically by Sherco for more precisely governing idling and engine braking, and ensuring perfect progressivity in power delivery… The secret for effective enduro racing!
